Add within 10 fluency
1. Hook
- Tap Read the lesson aloud (or a grown-up reads).
- Look at the pictures. Follow the numbered steps.
- Do the tap-and-try lab on this page. Do not skip it.
- Fill the short answers with a grown-up nearby.
- Do the quiz. Then teach it back in your own words.
You are at home on a computer or tablet. Everything you need is on this page.
Join 3 and 5. What total do you get? Check by adding the other way.
Then: lab → guided → quiz → teach it back. The lab is the lesson, not a decoration.
2. Teach
Today we learn: Add within 10 fluency.
Standards alignment: CCSS.MATH.CONTENT.1.NBT (domain-level; works with any state’s standards)
STEM this week is Add within 10 fluency: try it, then check a second way.
- Addition joins two parts to make a total (sum).
- Turn-around facts have the same sum: 3 + 5 = 5 + 3 = 8.
- Count on from the bigger number: 6 + 2 → say 6, then 7, 8.
Strategies: +0 stays the same. +1 is the next number. +2 is two jumps. Doubles: 1+1, 2+2, 3+3, 4+4, 5+5.
Start with the bigger number to count on less: 2 + 7 is easier as 7 + 2.
Fluency means you know the fact quickly, without counting every time.
- Fact: 3 + 5.
- Start with the bigger number: 5.
- Count on 3: 6, 7, 8.
- 3 + 5 = 8.
- Check: 5 + 3 = 8. Same sum.
Solve 2 + 6, 4 + 4, 1 + 8, 3 + 7. For each, name your strategy (count on, double, +1, or a ten fact).
Counting the starting number again ("5, 6, 7" for 5 + 3, getting 7). Say the start number, then count on.
Fast addition helps with money, scores, and later math.
